Inertial Navigation System to Boost Wind Turbine Installation Precision
Manufacturer of advanced inertial navigation systems (INS), Exail, has secured a contract to supply three Hydrins INS to Pliant Offshore, an offshore measurement specialist.The units will be integrated into Pliant Offshore’s installation measurement system to improve the accuracy and efficiency of wind turbine installations. Pliant’s technology is designed to provide real-time measurements of the inclination and position of structures, such as monopiles, during installation. The system uses 3D point cloud technology combined with laser sensors to measure and virtually reconstruct objects
Less is More with Gyroscopes
A new generation of fiber optic gyroscopes is taking the accuracy of inertial navigation systems higher and the payload lower.A fiber optic gyroscope (FOG) can now weigh less than three kilograms, less than two kilograms even, and be less than 200mm in diameter.As their host AUVs themselves shrink, FOGs are following suit, and as the AUVs go deeper and perform a wider range of data collection tasks, FOGs continue to be part of the GNSS-denied navigational systems that enable them to do it.The FOG sensors in an inertial navigation system measure changes in orientation of the AUV to support navigation
Sapura Bolsters Subsea Capabilities with Exail Rovins INS
Sapura, a Brazilian provider of subsea services, has recently acquired eight units of Exail Rovins Nano Inertial Navigation Systems (INS) to enhance its ROV capabilities in offshore installation of subsea equipment.Integrated into Sapura's fleet of remotely operated vehicles (ROV), Exail INS will help Sapura to lay flex pipes and deploy subsea hardware onto the seabed, such as templates and manifolds, rigid jumper spools or tie-in-spools.The Exai INS are said to be able to ensure highly accurate navigation down to 6000 meters.Rovins Nano, equipped with advanced sensors such as accelerometers and
Exail Opens New Office in Norway
;With this new office, we will be able to provide increased support to our growing base of customers in Norway, and more generally, Scandinavia.”Exail noted it has won major contracts in the region over the past years, both in the civil and defense markets. This includes the sale of inertial navigation systems for Norway’s U212 submarines and Coast Guard vessels, Finland’s Multi-role corvettes, as well as Sweden A19 and A26 submarines. Exail also has partnerships with civilian Scandinavian companies such as Teledyne Gavia, Nortek and RTS
Exail Launches All-in-one INS and DVL System
Subsea inertial navigation systems (INS) manufacturer Exail has launched the Rovins 9 DVL, a new all-in-one system for subsea vehicles that combines the best of inertial navigation and Doppler Velocity Log (DVL) technologies in one tightly integrated system.Described as highly compact for easy vehicle integration, the Rovins 9 DVL all-in-one design combines, in a single housing, Exail advanced Fiber-Optic based INS with a Nortek DVL. This tight integration of raw sensor data from both INS and DVL provides operators with highly accurate position, velocity, and attitude information, even in challenging

systems.STR’s investment includes the acquisition of iXblue’s long baseline (LBL) system; Canopus, making them the first rental company to offer the system for hire. Part of iXblue’s sparse LBL solution, Canopus brings together intelligent transponders, Ramses transceivers, Inertial Navigation Systems (INS), and Delph Subsea Positioning Software. It is also a third-party friendly solution able to be easily integrated within existing operational fields.The addition of iXblue’s Rovins and Rovins Nano Inertial Navigation Systems, as well as Gaps M5 ultra short baseline (USBL) system

plug & play, easy to deploy and to operate systems. They can be used on multiple offshore applications such as metrology or ROV/AUV positioning and are easy to integrate into the existing pool of equipment thanks to their open protocols. "When used in combination with iXblue Inertial Navigation Systems, innovative SLAM and Sparse LBL modes can be used, deploying a reduced number of transponders, and thus enhancing operational efficiency and cost-effectiveness," iXblue said."The intrinsic qualities of our LBL solutions, together with the comprehensive remote training of Van
Ashtead Technology Adds iXblue Tech to Rental Fleet
UK-based subsea equipment rental and solutions specialist Ashtead Technology said Monday it had strengthened its rental fleet with "a significant investment" in iXblue subsea navigation systems.The investment includes the addition of further Rovins and Rovins Nano inertial navigation systems as well as Octans attitude and heading reference systems which are now available to rent throughout the company’s nine international technology and service hubs, Ashtead said.""Based on fibre-optic gyroscope technology, iXblue navigation solutions have become a standard
